Abstract

See full text

A double latch lockset, or its kit form, generally includes first and second retractable latches connected by a drive assembly. The first retractable latch may be activated by a first inside and/or outside actuator, and the second retractable latch may be activated by a second inside and/or outside actuator that activates the second retractable latch (such as a deadbolt) independently of the first retractable latch. Movement of the first inside and/or outside actuator in a first direction simultaneously retracts the first and second retractable latches, and movement of the first inside and/or outside actuator in a second direction locks the second retractable latch. The first inside and outside actuators may be configured to move in the second direction without retracting the first retractable latch.
